MARK I-I. DOTY, OF HANNA. CITY, ILLINOIS.

FILTER.

To all whom t may concern:

`Be it known that I, MARK H. DoTY, a citi-` zen of the United States, residing at Hanna p City, in the county of Peoria and State of Illinois, have invented'certain new and useful Improvements in Filters, of which the following is a specification.

My invention relates to certain new and useful improvements Vin cistern filtersV and 1o more particularly to devicesserviceable for proper deflection and discharge of refuse as leaves and the like, from the filter housing in advance of the discharge of 'the water to the filter proper.

l It also includes a cut-off to intercept the flow of water to the filter under the circumstances of the cistern being full.

The structure to which I apply my improvementcomprises a housing member interposed in the pipe connection between the Water supply and the cistern containing the filtering materials, as charcoal, sponge and the like, or both, and my improvement comprises a perforated partition interposedin the housing and between the inlet thereinto and the filtering material, also an exit open` ing in one side of the housing to which the partition member inclines and deflects foreign matter. as leaves and the like, under Vnormal conditions of use. Italso includes a hinged closure member for said opening disposed ina manner to permit, and adapted to swing,'outwardly`to open said outlet under pressure of material or water passing thereto.

My invention also includes a supplemen-` tal non-perforated partition adapted to be inserted and to overlie the perforated partition under circumstances of a desire to in- 40 terrupt the fiow of water to the filter mate-V rial, and serves as a cut-off to discharge the water through the opening in the side of the housing.

My invention also includes a deector member interposed between the inlet to the housing and the partition to cause the water to be discharged at or near one side of the container.

Referring to the drawings-Figure 1 is V a front elevation of my invention with parts broken away to show the interior arrangement and construction of parts; Fig. 2 is a side eleva-tion of my invention, showing a hinged closure member raised from its closed position, and also showing an interior cut- Specication of Letters Patent.

off member broken away to disclose a perforate member.

Referringto the drawings7 2 and 3 indicate ordinary pipe connection leading to a cistern. p

,4 is a housing which is made of sheet metal and which I have shown in rectangular form somewhat larger than the size of the piping. However, this container may be madein any formor shape desired. I have provided attachment members 5 to aid in attachment for support of the housing, also I have provided `an openable door member 6 which is seatedron shouldered member 7 and attachable or is secured at its upper end 73 by means of yieldahle clipmember 8 which clip may be raised to allow the door 6 to be opened. While I have shown this door secured by clip member, yet it may be made to slide in ways at the 'sides for the open- 7 5 ing, if desired.

A box 9 is adapted to be disposed or placed within the container 4, the same being provided with a screened or ,perforated bottom member 10. This box 9 is supported 80 upon bracket members 11, fixed to each side wall of container 4. This box in practice is designedA to be filled or partially filled with filtering` material. In this instance I haveshown the box to contain charcoal as 12 and sponge material 13. Above the box member 9 I have provided a perforated partition member 14 preferably formed in arc shape as shown, said partition being in-' clined toward one side of the container and is designed to be fixed at its upper end in substantially the position shown` that is, one end at or near the top of container 4, and at the lower end at its juncture with the lower edge of an opening as 15 at one side of said 95 container, such inclined disposition being made to facilitate the deflection of materials toward said opening 15 and the downward curvature of the partition and the slight elevation at the discharge end above the lowest point of curvature to prevent too precipitate a flow of water discharged upon the partition toward the opening 15. I have also provided the deflector member 16 fixed at one side of the inlet into housing or container 4, preferably being curved in general form and extending partially across the inlet opening and toward the upper end of partition member 14. This deflector member is provided to direct and concentrate de- 110 liveryof water within the container 4--and to deflect it and in a sense spray it4 toward and upon the upper endofperforatedtpartie tion 14 so that water so caught will be deflected downwardly and its flow distributedy throughout practically the entire surfaceof'` said filtering material, thus aiding,` gener-` I have provided a partition 18 which I have hereinbefore spoken of as a cutoff. This partition has a similar curvature to that of perforated partition 14 and is ofthe same form as said partition 14 and is adapted to overlie'the latter when used. In Fig. 1 a portion ofthe-partition 14 has been broken away, similar to the showingiinFig. 2, but in practice this partition will be continuous from endto end. This partition 1S is provided with an end wall member 19l shown in dotted lines in Fig. 1 which serves to'give it a trough-like f'orm at its side nextv to the door member 6. In practice such a side wall member may. be provided if` desired, at each side of saidpartition. The partition is also provided with a downwardly extending member 20 which is de signed when the partition is inserted within compartment 4, to extend through openingy 15 and' overlie the downwardly inclinedV apron member 21thatextend`sA from theV side wall of housing 4; This partition 18 is de signed-to beused only as a cut-off'to cause Copies of'ths patent' may be obtained for five the water*l flowing through" the connection to 'be discharged from opening 15, to prevent its 'entrance into'thelcistern. Under normal conditions of use of the filter, this partition is-removed.

I have shown herein one form of my invention for the purpose of illustrating the principle` of operation. I do not,vhowever, wish to be confinedto detail form of parts herein shown but claim generally allforms and combinations of parts that come within the principle herein. disclosed.

In a device of the class described, in com` bination, a housing member providedvwith a removable side wall, aninlet opening atT its top, a main-discharge opening inits bottom, and an auxiliary` discharge opening in one` of its fixed` sides, a filter material container fitting snugly withinithe housing below the auxiliary outlet V'and adapted` to ebe. inserted andV withdrawn through' the removable f' side wall, a curved perforated partition-extend#V ing. across the housing fromtheauxiliary outlet andinclineddownwardly toward the same, the end of saidpartition adjacent .said` outlet havinganiupward curvature to retard the flow ofV water through the outlet, ,a fixedV deflector in the housing .below the inletopening to direct incomingunlilteredwater toward the higher end-of the. perforated par-l tition that it may pass downwardly overthe same, a hinged door normally closingY the auxiliary discharge but capable of swing ing open under internal pressure,1 and removable -means for insertion inthe housing over the perforated partition. to dire( :t a'll0 thel water outwardly through'. the. auxiliary,"
